What is a Walkie-Talkie?

A walkie-talkie is a hand-held, portable, two-way radio transceiver. Its characteristics include.

Half-duplex Channel, which means that only one radio transmits at a time, though any number can listen. and

A "push-to-talk" (PTT) Switch, that starts transmission.

Hand-held transceivers may be used to communicate between each other, or to vehicle-mounted or base stations. Walkie-Talkies typically resemble a handset, slightly larger in size, with an antenna on the top of the unit. A walkie-talkie's speaker can be heard by the user and those in the user's close vicinity.

Walkie-Talkies are formally known as a handheld transceiver, or HT

"Its development has been credited to Donald L Hings, radio engineer Alfred J. Gross, and engineering teams at Motorola during the Second World War."
